PARE: A Stateful Benchmark for Proactive AI Assistants

This work exposes a core blind spot in proactive AI assistant research: benchmarks that flatten apps into stateless APIs can't test real-world anticipation and timing. The proposed PARE framework models applications as finite state machines, enabling stateful user simulation and a 143-task benchmark across communication, productivity, and scheduling domains.

Spotify expands AI push with conversational music assistant for Premium users

Spotify is testing a ChatGPT-style music assistant for Premium users, letting them chat about listening history, refine playlists with natural language, and discover songs conversationally. It blends Spotify’s own AI with multiple model providers, betting that conversational interfaces will outpace search and recommendations in a catalog with millions of tracks.

Behavioral Privacy Leakage in Agentic Negotiation

Autonomous negotiation agents are increasingly deployed in high-stakes settings like insurance and procurement, where cryptographic techniques protect explicitly disclosed constraints. However, this paper exposes a subtler threat: behavioral privacy leakage, where an adversary infers private constraints from observable negotiation dynamics—concession trajectories, timing, and convergence patterns. The tension is that even if the agent never reveals its reservation price directly, its behavior during rounds of bargaining leaks enough information for inference attacks.
